Below I have listed most of the major night sky events for this month, birthdays, events in history etc. I have also listed all resources used to generate these monthly calendars at the bottom of the post so dig in, learn and enjoy! Also; if you notice something that I didn’t add that you think should be here, or if something’s incorrect definitely let me know!
Here’s a list of major 2015 Celestial Events here: https://danspace77.com/2015-celestial-events/

How about Meteor Showers for 2015? https://danspace77.com/2015-meteor-showers/

WERE YOU BORN ON A FULL MOON?! This great page from Moon Giant shows you what phase the Moon was in when you were born; check it out. (This may not work on your phone): http://www.moongiant.com/birthday_moon/

All dates and times were calculated using Military Time & Universal Time (UTC) and I also throw in eastern U.S. time (EST or EDT depending on whether its Daylight Savings or not) but beware, early morning events for UTC will actually likely be late night events on the previous date for the US. For example if something is scheduled to occur at 02:00 UTC on the 14th, that’s 21:00 EST on the 13th.

Another important thing to remember is that a calendar day is actually daylight sandwiched between two darks so when an event says, March 29 for example, you’ve got to check the time because March 29 could very well be in the morning before sunrise and not that coming night.

Finally, calculating events on the Moon is that it’s not as simple as “Ok it’s 40% illuminated so we should see this.” I wish it was that easy but because of libration, locations on the disk of the moon move slightly as we see them. One month an event could occur at 52% illumination and the next month it could occur at 54% illumination etc.

01 (Sun) – Entering the month the Moon is 20 days old in its 29.53 day Synodic Cycle and 71% illuminated in its waning gibbous phase.

01 (Sun) – Fall Back! For those to whom it applies, we turn the clocks back at 02:00 back to 01:00. Technically from 01:59:59 to 01:00. This means we change time format from Daylight Time (DT) to Standard Time (ST). The east coast of the United States for example is currently 4 hours behind Universal Time (UTC or UT) but once we fall back we will then be 5 hours behind.

03 (Tue) – Last Quarter (3rd Quarter) Moon occurs this month at 12:55 UTC (07:55 EST). Though the quarters of the Moon occur at exact times, as far as viewing goes you can call it the entire night and be close enough.

03 (Tue) – Walther Sunset Ray will occur around 22:27 UTC (16:27 EST). Located in the ancient 145 kilometer (90 mile) Necterian age crater named Walther (Formerly Walter or Valtherus) is a special treat that occurs monthly for a matter of a few hours when illumination is around 44%. On the western rim of the crater there’s a notch and when the Sun is setting low on the lunar horizon (When the crater is near the terminator) light penetrates the notch, creating a vast triangle or “V” shaped light ray across the craters floor that ends as it illuminates the central peak of the crater. Walther Crater a heavily eroded crater located in the Lunar Southern Highlands at the Selenographic Coordinates (Definition below) of Latitude: 33.1°S / Longitude: 1.0°E. It’s named after German astronomer Bernhard Walther. This crater also has a sunrise ray that instead of a light ray is a long shadow cast by the central peak.

November 3, 1930: Birth of X-15 pilot, Bill Dana.

November 3, 1957: Launch of Sputnik 2: Dog Laika “Barker” became first animal in space and first to die in space. Remained dead in orbit for 162 days.

04 (Wed) – Pico Mons Sunset. The day of or day after last quarter (around 50% illuminated) the setting Sun hits Pico Mons in Mare Imbrium, near Crater Plato and casts a long shadow along the lunar plains.

04 (Wed) – Sunset on the lunar scarp; Rupes Recta or the “Straight Wall” is visible about the day of or day after last quarter (about 45-50% illuminated) the setting Sun causes it to look white as it illuminates the slope. Two weeks later, during lunar sunrise after first quarter it will appear black.

05 (Thu) – 17 (Tue) As of Thursday the 5th we are on the verge of this month’s new moon (Lunation 1149). This week presents nights that are the absolute BEST nights to get out and observe Deep Sky Objects (DSOs) because you won’t have to look through the spotlight that is the Moon. Night skies without the Moon are significantly more productive for viewing and photography ANY night sky object (besides the Moon itself of course). For the lucky ones, this week offers the amazing spectacle of the extreme crescent moon, both waning in the east & waxing in the west.

05 (Thu) – The CURTISS CROSS, is a creation of shadows throughout craters Gambart and Parry which create an “X” shaped formation and will occur around 05:07 UTC (00:07 EST). The Curtiss Cross is associated with the third (last) quarter Moon and forms about14 hours past the third quarter mark.

07 (Sat) – In the east before sunrise the thin waning crescent Moon will join Venus and Mars with Jupiter not too far away.

07 (Sat) – The Moon reaches Ascending Node at 15:53 UTC (10:53 EST).

07 (Sat) – Apogee Moon occurs at 21:50 UTC (16:50 EST) where the Moon is at its furthest point from Earth in its current orbit and will be subtending at 29’ arc minutes from a distance of 405,708 km (252,095 mi).

11 (Wed) – New Moon (LUNATION 1149) occurs at 17:47 UTC (12:47 EST). Though the quarters of the Moon occur at exact times, as far as viewing goes you can call it the entire night and be close enough.

November 11; Veterans Day.

November 12, 2014: Philae lands on Comet 67P. 1st ever comet landing.

13 (Fri) My single favorite phase of the Moon occurs around 95 % illumination just after full phase. I call it the “Full Crater Chain” and it’s when the terminator runs right through Mare Crisium. The chain runs up through Cleomedes, Burckhardt, Geminus, Messala, Endymion and even more impressively below Crisium through Langrenus, Vendelinus, Petavius and Furnerius. If you catch it just right you can enjoy a secondary treat as Petavius’s central peak becomes illuminated and shines alone in the darkness of the crater itself. (NOTE: With libration it may not fully form month to month.).

November 14, 1930: Birth of Ed White.

November 14, 1933: Happy Birthday Fred Haise.

November 14, 1969: Launch of Apollo 12 & 1st use of KSC’s countdown clock.

17 & 18 (Tue night & Wed morn): Leonids Meteor Shower: Peak viewing will be on the night of Tuesday the 17th and Wednesday the 18th before sunrise. Peak rate this year will be a modest 25-ish per hour and the 35% waning crescent moon will be a late riser and will impact the show at least moderately. With the name Leonids, you will obviously want to look in the general direction of the constellation Leo the Lion. The parent body of this event is shower by Comet 55P/Temple Tuttle.
As always, don’t put all your eggs in one basket. Peak might be 12 & 13 but active dates should range from mid-July to late-August. Obviously the further from peak you get the less you will see but you never know if the weather will wash out peak viewing nights. So if it’s clear and near have a look!
Peak night is usually a given night and next morning with the “next morning” being the absolute best time to watch. In fact the closer to morning twilight you can get, the better…..here’s why. If you view the solar system from the top, planets orbit the Sun in a counter clockwise motion, we also rotate in a counter clockwise motion. That means just before sunrise the Earth is pointed in the direction of travel of the Earth itself and meteors are mere “bugs (Or if you prefer; “snowflakes”) hitting the windshield” of Spaceship Earth.

18 (Wed) – LUNAR-X also known as the PURBACH or WERNER CROSS is scheduled to begin forming the “X” around 17:37 UTC (12:37 EST). The Lunar-X is the big, more prominent brother to the Curtiss Cross. This “X” is created by shadowing throughout the rims and ridges of craters LaCaille, Blanchinus and Purbach. The “X” formations occur along the terminator (where “day” meets “night” across the Moon). It typically begins just after first quarter when the Moon is approximately 53% illuminated.

18 (Wed) – MAGINUS SUNRISE RAY will occur around 09:46 UTC (05:46 EST). At the right times and as the Sun rises over the Crater Maginus (Near the terminator) a beautiful sun ray shines through a break in the craters eastern wall. The result is a vast triangle or “V” formation of light cast upon the crater floor for a period of a few hours. Maginus Crater (Named after Italian astronomer Giovanni Antonio Magini) is a pre-Nectarian impact crater located in the southern lunar highlands and to the south east of Tycho Crater. It’s 110 miles (177km.) and has been extremely eroded by subsequent impacts on or near the site through the millennia. Its selenographic coordinates (Definition below) are Latitude: 50.5°S / Longitude: 6.3°W.

November 18, 1923: Birth of Alan B. Shepard.

November 18, 1929: Birth of X-15 pilot, Pete Knight.

19 (Thu) – Pico Mons Sunrise occurs the night of or the night after first quarter (around 62% illuminated) the rising Sun hits Pico Mons in Mare Imbrium, near Crater Plato and casts a long shadow along the lunar plains.

19 (Thu) – Sunrise on the lunar scarp; Rupes Recta or the “Straight Wall” is visible the night of or the night after first quarter (around 60% illuminated) the rising Sun causes it to look black as its shadow is cast. Two weeks later, during lunar sunset it will appear white.

19 (Thu) – First Quarter Moon is the Moon watchers paradise. Occurring at 06:28 UTC (01:28 EST), First Quarter Moons and the waxing crescent phase leading up to it offer some of the most visually stunning views the Moon has to offer. Most of us will take the beautiful curves, valleys and shadows of a 1st Quarter Moon over a Full Moon ANY day. Though the quarters of the Moon occur at exact times, as far as viewing goes you can call it the entire night and be close enough.

November 19, 1969: Apollo 12 touches down on the lunar surface.

November 20, 1889: Birth of Edwin Hubble.

November 20, 1998: 1sr piece of the ISS launched. Zarya “sunrise” module from Baikonur.

November 20, 1969: Apollo 1 astronauts Conrad & Bean visit Surveyor 3 on the Moon.

21 (Sat) – The Moon reaches Descending Node at 13:56 UTC (08:56 EST).

23 (Mon) – Perigee Moon occurs at 20:09 UTC (15:09 EST) and is when the Moon is at its closest point to Earth in its orbit. It will be subtending at 33’arc minutes from a distance of 362,822 km (225,447 mi).

25 (Wed) – The Full Moon will occur at 22:44 UTC (17:44 EST). Though the quarters of the Moon occur at exact times, as far as viewing goes you can call it the entire night and be close enough. (Name information provided by The Farmer’s Almanac). Full Beaver Moon – November: This was the time to set beaver traps before the swamps froze, to ensure a supply of warm winter furs. Another interpretation suggests that the name Full Beaver Moon comes from the fact that the beavers are now actively preparing for winter. It is sometimes also referred to as the Frosty Moon.
Full Moon Note: Many people actually find observing the Full Moon through a telescope or binoculars almost painful due to its brightness. One way that we curb this issue (at least in telescopes) is with neutral density filters. ND filters range anywhere from 20% light block to 80% light block and they’re pretty cheap. I don’t usually use them but I have a 50% on hand in the event someone needs it. Just be careful because for some companies, an ND25 means 25% of the light is blocked while some mean 25% of light passes through so make sure before you buy.

November 26, 2011: Launch of MSL Curiosity.

November 27, 1955: Happy Birthday Bill Nye.

27 (Fri) – The Moon reaches its Greatest Northern Declination of +18.22 degrees.

November 29, 1961: Launch of Mercury-Atlas V and the 1st American to orbit the Earth; Enos the chimp.

30 (Mon) – Leaving the month the Moon is 20 days old in its 29.53 day Synodic Cycle and 77% illuminated in its waxing gibbous phase.

***Definition of LIBRATION (basically) – Is an oscillation of an orbiting body relative to another. OK, so…We know the Earth/Moon system is tidally locked so we always see the same side of the moon. Due to libration, we ACTUALLY see about 60% of the Moon instead of what you may intuitively think of as a 50% measurement. That’s because the Moon oscillates slightly as it rotates and orbits Earth. So, on occasion and with a keen eye we can see a little further “around the corner” north, south, east and west on the moon by a couple degrees.

***SUBTENDING Explained – Definition: The angle formed by an object at a given external point. The moon subtends an angle of approximately 0.54° (32 arc minutes) to an observer on the Earth. Of course, the moon’s orbit is not constant or exactly circular, so this varies a little, but not by very much. If you hold up your thumb at arm’s length, you can easily cover the full moon. This means your thumb subtends a larger angle to your eye at arm’s length than the moon does at 380,000 kilometers. In general, the closer you are to a particular object the larger that subtending angle.

***SELENOGRAPHIC COORDINATES Defined – Selenographic coordinates are used to refer to locations on the surface of Earth’s Moon. Any position on the lunar surface can be referenced by specifying two numerical values, which are comparable to the latitude and longitude of Earth. The longitude gives the position east or west of the Moon’s prime meridian, which is the line of longitude passing through the point on the lunar surface directly facing Earth. (See also Earth’s prime meridian.) This can be thought of as the midpoint of the visible Moon as seen from the Earth. The latitude gives the position north or south of the lunar equator. Both of these coordinates are given in terms of degrees. Astronomers defined the fundamental location in the selenographic coordinate system by the small, bowl-shaped satellite crater ‘Mösting A’. The coordinates of this crater are defined as: Latitude: 3° 12′ 43.2″ South / Longitude: 5° 12′ 39.6″ West. The coordinate system has become precisely defined due to the Lunar Laser Ranging Experiment. Anything past 90°E or 90°W would not be seen from Earth, except for libration, which makes 59% of the Moon visible.
